WATER PUMP 'FOR MOTOR VEHICLES.

Application filed July 23, 1921. Serial No. 487,019.

To all whom; it may concern:

Be it known that I, JOHN L. DABADIE, a citizen of the United States, residing at Stockton, county of San Joaquin, State of California, have invented certain new and useful Improvements in Water Pumps for Motor Vehicles; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the w accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to a pump for increasing and aiding the speed of circulation w of the cooling water of Ford engines as installed in automobiles of the same name.

The principal object of my invention is to provide a water pump for the above purpose which may be easily attached between the radiator and engine of any Ford car in place of the usual water-intake pipe, and Without necessitating any alterations or additions being made, other than to take out a portion of the pipe usually provided and installing my improved pump in place thereof.

Another object is to construct the pump in such a manner that it will not be necessary to detach or demount the main body portion of the pump when it is desired to inspect or remove the pump runner, shaft,

' etc.

A third object is to so arrange the device that the pump runner may be driven by the same belt now used to drive the fan, by merely adjusting the setting of the latter. This of itself is 'a valuable feature, since in the not infrequent event of a belt breaking, a standard Ford belt can be obtained almost anywhere, while an odd length would probably be hard to get.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views Fig. 1 is a front-end outline of a certain type of engine, showing my improved pump installed therewith.

Fig. 2 is a sectional side view of the pump detached. 7

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes in general the body of the pump, formed or cast in one piece, and which comprises in detail a pipe 2 which sets at an angle equal to that of the waterintake pipe as provided on the car, and a portion 3 projecting up from the member 2 in a vertical plane.

A partition 4 divides the members 2 and 3 into two portions 5 and 6, the former, at the front end forming the intake passage from the radiator, while the latter, at the rear end, forms the discharge to the engine.

Turnably mounted in the upper end of the portion 6 is a centrifugal runne 7 fixed on a shaft S-journaled in the body 1 and projecting therethrough at the forward end, and also in a removable cap 9 fixed on the rear end of the body 1 of such a size as to permit the runner to be removed when said cap is taken ofi The partition 4 has an orifice therethrough concentric with the shaft and larger than the same, 'so as to allow the water in the portion 5 to be drawn in by the runner and discharged thereby into the portion 6, the latter being formed with a discharge spiral 6 as usually provided to co-operate with a pump runner.

On the outer end of the 10 in vertical alinement ley 11 of the engine and positioned partly thereunder as shown in Fig. 1, the pump being set at a transverse angle, also as shown in order to allow this to be done.

In this manner, the usual belt 12 which drives the fan pulley may be employed, merely by loosening or adjusting the arm 13 on which the fan pulley is mounted enough to allow the belt to be passed about the outer face of the pulley 10 and frictionally engage the same.

Short lengths of hose 14 are coupled on to the pipe 2 on both ends of the same, in order to make the necessary connections to the engine and radiator pipes, and to prevent vibration being transmitted to the latter.

In order to hold the pump rigidly in place, an eye-bolt 15 whose eye is engaged and clamped by one of the cap-screws or nuts 16 on the timer gear case 17 of the engine shaft 8 is a pulley with the fan puladjacent the upper horizontal face of the case 17, this pad having a set screw 21 projecting therethrough in order that said screw may be turned to bring its end to rest firmly on the case 17. In this manner, the position of the pump may be fixed to a nicety, while no additional bolts etc. other than those already on the engine are used to hold it in place.

From the foregoing description it will be readily seen that I have produced such adevice as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of said extension having a what I claim as new and useful and desire to secure by Letters Patent is:

A water pump for motor vehicles including a one-piece body consisting of a straight pipe portion adapted .tobe interposed in the cooling-water line of the motor, a hollow extension projecting upwardly from the pipe portion intermediate its ends, and a transverse partition orificed adjacent its uppe end and dividing said extension and pipe into two chambers, one of the walls of bearing for a shaft in alinement with the partition orifice and the other wall having a similarly alined and removable cap clear of the pipe portion and of a size to permit of the insertion of a runner therethrough and into the adjacent chamber.

In testimony whereof I afiix my signature.
